The aggressively-styled Infiniti M56x AWD is a luxury sedan for those who prefer the backcountry to the country club. With a sizable 420-horsepower, 5.6-liter V8 that shoots the sporty sedan from 0 to 60 in 4.9 seconds, the M56x doesn't skimp on power; however, its real selling point is its handling. Featuring intelligent all-wheel drive and a drive mode selector with "Snow mode," the Infiniti M56x AWD is perfect for winter weekend getaways to the mountains.
